Brush

ABSTRACT

A brush has a handle having an elongated recess defined in a flat bottom face thereof, a connector configured to be securely received in the elongated recess and having an oval through hole, and a bundle of bristles extending through the oval through hole to securely engage a bottom face defining the oval through hole. With the elongated recess, adjustment to the length of the bundle of bristles and the retainer to secure the connector inside the recess are not required.

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a brush, and more particularly to a brush having bristles economically and efficiently received in the handle easily. The brush has an elongated recess defined in the handle to receive therein glue so that the manufacturer will not have to carefully measure the quantity of glue to be applied and the bristles are able to be inserted into the elongated recess directly without any other retaining accessory to secure the engagement between the bristles and the handle.

[0003] 2. Description of Related Art

[0004] With reference to FIGS. 6 and 7, a conventional brush (50) has a handle (51), a connector (52) and a bundle of bristles (53). These bristles are often of high quality to ensure a satisfactory result when the brush is in use. However, in order to reduce costs of the finished brush, manufacturers may consider providing only the quantity of bristles necessary.

[0005] The handle (51) has a flat bottom face formed to correspond to a first chamber (521) in the connector (52). The bristles (53) correspond to a second chamber (522) in the connector (52). To reduce the quantity of the bristles (53) needed, a baffle (60) is provided to be received in the second chamber (522).

[0006] When this kind of brush is assembled, it is noted that the bristles (53) are inserted into the second chamber (522) after the length of the bristles (53) is adjusted. After the bristles (53) are well inserted into the second chamber (522) of the connector (52), a proper quantity of glue (not shown) is applied into the second chamber (522). After the glue is dried, the flat bottom face of the handle (51) is then securely received in the first chamber (521) by retainers (70) such as staples or nails.

[0007] The baffle (60) may be put inside the second chamber (522) before the bristles (53) are received in the second chamber (522) which in turn is filled with glue to securely retain the bristles (53) and the baffle (60) in the second chamber (522).

[0008] Due to the structure of this kind of brush, the assembly process suffers from several disadvantages, such as:

[0009] 1. Manual adjustment of the length of the bristles with respect to the connector is required. Because of the production of different sizes of brushes, an adjustment to the length of the bristles relative to the connector is required, which increases the manufacture cost.

[0010] 2. Measurement to the quantity of glue is necessary. Because the glue is used to adhere the bristles inside the second chamber and because different sizes of the brushes are required, the adjustment to the glue quantity is required.

[0011] 3. Retainers are required to secure the engagement of the handle to the connector.

[0012] To overcome the shortcomings, the present invention tends to provide an improved brush structure to mitigate and obviate the aforementioned problems.

SUMMARY OF THE INVENTION

[0013] The primary objective of the present invention is to provide an improved brush having a recess defined in a flat bottom face of the handle so that no adjustment to either the length of the bristles or the quantity of the glue is required.

[0014] In order to accomplish the foregoing objective, the brush of the present invention has a handle with an elongated recess defined in a flat bottom face thereof. A connector is configured to be received in the elongated recess and has an oval through hole defined to correspond to the elongated recess of the handle. A bundle of bristles is provided to pass through the oval through hole and received in the elongated recess. With the structure described above, there is no need to adjust the length of the bristles. Adjustment to the quantity of the glue is also eliminated because the glue is directly poured into the elongated recess. When the glue in the elongated recess secures the bristles, it additionally secures the connector that is also received in the elongated recess.

[0015] Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT

[0023] With reference to FIGS. 1, 2 and 3, the brush (10) in accordance with the present invention has a handle (11), a connector (12) and a bundle of bristles (13).

[0024] The handle (11) has an elongated recess (111) defined in a flat bottom face thereof.

[0025] The connector (12) is configured to be received in the elongated recess (111) and has an oval through hole (121) defined to correspond to the elongated recess (111).

[0026] When the brush (10) is assembled, the bristles (13) first extend through the oval through hole ( 121) of the connector (12) and then engage a bottom face defining the elongated recess (111). When one distal end of the bristles (13) engages the bottom face defining the elongated recess (111), the connector (12) is also received in the elongated recess ( 111). Therefore, the length of the bristles (13) is uniform and no extra adjustment is required to further adjust the length of the bristles (13).

[0027] Thereafter, glue is poured into the elongated recess (111) to therefore secure the connector (12) and the bristles (13) in the elongated recess (111). It is noted that the purpose of the oval through hole (121) is to expedite the extension of the bristles (13) through the oval through hole (121).

[0028] With reference to FIG. 4, another preferred embodiment of the present invention is provided with a baffle (122) received in the oval through hole (121) to divide the oval through hole (121) into two compartments (123). With the baffle (122) received in the oval through hole (121) of the connector (12), the quantity of the bristles (13) is able to be reduced.

[0029] With reference to FIG. 5, still another preferred embodiment of the present invention has two baffles (124) received in the oval through hole (121) of the connector (12) to divide the oval through hole (121) into three compartments (125). With the two baffles (124), the quantity of the bristles (13) is able to be further reduced, thus further saving costs in the manufacture of the brush. so that the user is able to use the quantity to produce brushes for different purposes.

[0030] It is concluded that the present invention has advantages such as:

[0031] Easy and simple assembly;

[0032] Minimum labor; and

[0033] Low material cost

[0034] It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
